Description

[Detailed description of the invention] Industrial application field The present invention relates to a gate whose door body can be attached to a post with the door body selected to open either inward or outward. The present invention relates to a gate using a hinge device that fits a vertical stile of a door body into a shaped mounting groove and fastens with screws.

Prior Art Various hinge devices for gates that can hinge the door body in either the inward or outward opening state have been proposed and put into practical use. A hinge device that uses an armrest bracket that fits into the vertical frame and fastens with screws has a good appearance, can firmly fix the armrest bracket to the door body, and is easy to position the armrest bracket to the door body. It is often used because it is easy.

As shown in FIG. 1A, such a hinge device includes a screw supporting wall 3 on one side of the base 2 in the width direction, and a frame holding wall 4 on the other side, which are integrally formed in the same direction and extend in the vertical direction. Using the armrest bracket 1 having a U-shaped mounting groove 5, fit the vertical stile 7 of the door body 6 into the mounting groove 5, and tighten the vertical stile 7 with the screw 8 screwed into the male screw hole of the screw support wall 3. There has been provided a device in which the armrest fitting 1 is fixed to the door body 6 by pressing it against the frame holding wall 4 (Japanese Utility Model Publication No. 56-177000). However, the gate using this hinge device is not suitable for the back side of the vertical stile 7, that is, the screw 8
A groove 9 is formed with the top and bottom left on the side, and the screw 8 presses the groove 9, so the armrest fitting 1 cannot be attached to or removed from the vertical stile 7 unless the screw 8 is completely retreated from the groove 9. could not be done, and the elbow bracket 1
The work of attaching and detaching is troublesome. In addition, in this type of hinge device, the distance between the screw support wall 3 and the stile clamping wall 4, that is, the width of the mounting groove 5 is generally wider than the thickness of the stile 7, and the stile 7 is held closely against the stile clamping wall 4. Then, a gap S is created between the screw support wall 3 and the vertical stile 7, and due to this gap S, the door body 6 is installed in an inclined state with respect to the armrest fitting 1, as shown by the two-dot chain line in FIG. 1A. I often end up doing this.

Further, as shown in FIG. 1B, the tips 3' and 4' of the screw support wall 3 of the armrest fitting 1 and the frame clamping wall 4 are bent inward at approximately right angles to form a mounting groove 5'. A hinge device has been proposed in which the vertical stile 7' of the door body 6' is made thicker than the other end, and the vertical stile 7' is fitted into the mounting groove 5' (Japanese Utility Model Publication No. 11439/1983). . but,
In a gate using this hinge device, the armrest fitting 1 is fitted from the vertical end of the vertical stile 7'.
Attaching and detaching the armrest fitting 1 is troublesome. Also, in this hinge device, since the width of the mounting groove 5' is wider than the thickness of the stile 7', when the stile 7' is brought into close contact with the stile holding wall 4, the stile 7' and the screw support wall 3, and this gap S often causes the door body 6 to be installed at an angle with respect to the armrest fitting 1, as shown by the two-dot chain line in Fig. 1B. .

When the door body 6 is tilted relative to the armrest fitting 1 in this way, it looks unsightly, and the latch for keeping the gate closed cannot be locked. When it returns to its correct state, the clamping pressure on the vertical stile becomes weaker and the door body comes off.

Purpose of the invention Although the invention uses a hinge device of the type in which a vertical frame is inserted into a U-shaped mounting groove and fixed with screws, it is easy to attach and detach the armrest bracket, and Even if there is a gap between the supporting wall and the vertical stile,
To provide a gate that can be installed in the correct state simply by pressing against a stile holding wall without the door body being installed in an inclined state with respect to an armrest metal fitting.

According to the present invention, the above object is to provide a protrusion on the surface of the vertical stile on the side of the screw support wall, with the surface on the side of the main part of the door body being an inclined surface, on the edge opposite to the main part of the door body. The tip of the frame retaining wall is bent toward the screw support wall so that its inner surface is an inclined surface that is inclined with respect to the frame retaining wall, and the female screw hole is formed in the screw support wall so that the screw hole is closer to the elbow than its center line. This is accomplished by forming a base portion of the metal fitting at a location facing the inclined surface, and screwing a screw having a truncated conical tip into the female threaded hole.

Embodiments Hereinafter, the present invention will be explained based on embodiments shown in the drawings.

9 to form a U-shaped mounting groove 40,
The base portion 37 is fitted into the groove 35 of the boss member 31. The frame clamping wall 39 has a tip portion 41 bent inward, that is, toward the screw support wall 38 side, to form a support recess 42 between the base portion 37 and the tip portion 41, and the inner surface of the tip portion 41 is bent inward, that is, toward the screw support wall 38 side. 39, the inclined surface 43 has an angle of less than 90 degrees, preferably between 30 and 80 degrees. Two screw holes 44 into which the aforementioned two screws 23 are individually screwed are formed in the screw support wall 38 at locations spaced apart in the vertical direction. Each screw hole 44 is formed at a position closer to the base 37 than the center line 45 when the vertical stile 15 is properly fitted into the mounting groove 40, that is, when the side wall 16 of the vertical stile 15 and the base 37 of the armrest fitting 21 are in close contact with each other. The side portions are formed at positions facing the inclined surfaces of the protrusions 55 of the vertical stile 55.

The width of the mounting groove 40, that is, the distance between the screw support wall 38 and the frame holding wall 39, is the width of the vertical frame 15 of the door body 11, and in particular is slightly larger than the width of the side wall 16. In addition, the width of the support groove 42, that is, the base 37
The minimum distance between the end portion 41 and the side wall 1 of the vertical stile 15 is
The thickness is almost the same as that of 6. Further, the distance between the screw support wall 38 and the edge of the tip portion 41 of the frame holding wall 39 is slightly smaller than the width of the vertical frame 15 on the side wall 16 side.

The connecting shaft 22 has a head portion 46 at the upper end, and the shaft portion 47 is connected to the boss portion 33 of the armrest fitting 21,
After passing the washer 48 through the boss portion 28 of the elbow fitting 20 in that order from above, attach the E ring 49 to the lower end.
It is installed by providing a. Each screw 23 is
In the illustrated example, it is a set screw, and the tip end 50 facing the stile 15 is formed into a truncated conical shape.

The elbow bracket 21 is assembled with each screw 23 loosened.
The tip edge of the side wall 16 of the vertical stile 15 is fitted into the support recess 42, and the side wall 16 of the vertical stile 15 is attached to the base 3 of the mounting member 32.
The vertical stile 15 is mounted by screwing in each screw 23 and pressing the side wall 16 of the vertical stile 15 against the stile clamping wall 39 of the mounting member 32.

When attaching the armrest fitting 21 to the vertical stile 15 in this way, since the distance between the screw support wall 18 and the edge of the tip part 41 is slightly smaller than the width of the vertical stile 15 on the side wall 16 side, the side wall 16 Fitting can be done as shown in FIG. 4 by simply rotating the armrest fitting 21 around the support recess 42 in the clockwise direction in FIG. When removing the armrest fitting 21 from the vertical stile 15, it is sufficient to loosen the screws 23, 23 and then rotate the armrest fitting 21 counterclockwise in FIG. 4 around the support recess 42. Therefore, there is no need to attach or detach the armrest fittings 21 from the vertical ends of the vertical stile 15.

In this hinge device, in order to attach the door body 11 in an inward-opening state, as shown in FIG. 3 and FIG.
